(30 + 3√85) ≈ 57.659 (30 − 3√85) ≈ 2.341
I was able to get the number 30 by adding 4 odd numbers 3 + 7 + 5 + 15 = 30 But i can't add 5 odd numbers to get 30
28 2 27 3 29 1 etc...
2*3*-5 = -30 3*-5 = -15 -5 - 5 - 3 - 2 = -15

It means you are counting in increments of 5. 5+5=10, 10+5=15. If by the word "mean", you are talking about the average, then the mean is 10. To determine the average of any group of numbers, add the numbers and divide the total by the number of numbers added - (does this makes sense?) Example: 5 + 10 + 15 = 30. Divide 30 by 3 (you added 3 numbers together to get the total) and the average is 10. Hope this helps.
It is 30 because 2*3*5 = 30
it means the average. add up all of the numbers and divide by the number of numbers you added. for example, 10+ 10+10=30 the mean is 30 divided by 3 = 10 the average! A nasty average?
